Porsche 996 TT Repair Manual page 171

• There are two marks on the dipstick located on the reservoir cap. One side bears the mark Cold for a
cold engine (approximately 20° C) and the other Hot for a hot engine (approximately 80° C).
• Check the fluid level (Pentosin CHF 11 S) with the engine stationary and cold (approx. 20 °C).
CAUTION
Danger of damage to property if too much Pentosin CHF 11 S is filled or if it comes in contact with the
coolant hoses when topping up or filling in.
• Observe the following specifications in order to avoid overfilling and thus overflowing.
• Multiple steering operations (manoeuvring) or/and actuating the clutch with the engine switched off
change the fluid level in the reservoir (actuating the clutch is not valid for the GT2). Fluid level rises.
In this case, the engine must be run for approx. 20 seconds immediately prior to the fluid level check.
• If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY.
Replace visibly swollen coolant hoses.
•
1. Start engine and run it at idle speed for approx. 20 seconds. Switch off engine.
2. Open the engine cover.
3. Open reservoir cap.
4. Wipe off the dipstick. Close and then reopen the cap. The fluid level should lie in the hatched area beneath
the "Cold" mark (mark = maximum level at 20° C). Top up with Pentosin if necessary. *The upper "Hot"
mark is intended for a fluid temperature of 80° C.
• Do not add too much Pentosin! The respective marks are for the maximum fluid level at the "COLD"
or "HOT" temperature.
• If assembly work was performed previously, check the fluid level with the engine idling and without
operating the steering.
